基于虚拟现实的机场消防救援虚拟演练平台

针对机场实地消防应急演练中人力物资消耗多、演练组织协调难,以及桌面式演练中情景感知支持不足等缺陷,提出一种基于虚拟现实技术的机场消防应急救援虚拟演练平台。基于虚拟现实技术的特点,采用三维建模技术构建机场消防救援场景中典型三维实体模型。利用粒子系统实现火灾虚拟场景及应急处置特效,并基于Unity3D引擎实现教员和学员人机交互界面。借助于虚拟现实头盔和手柄支持学员进入虚拟演练场景展开交互。平台测试表明:平台具有良好的易用性、稳定性和实时性,可以支持实现低成本、高沉浸感的机场消防救援虚拟演练。

Airport Fire Emergency Rescue Virtual Drill Platform Based on Virtual Reality technique

A virtual reality technique-based airport fire emergency rescue virtual drill platform is proposed,aiming at resolving the defects of large manpower and material consumption,difficulty in rehearsing organization in the field emergency rescue drill,and the insufficient situation awareness support in desk exercise for emergency rescue plan.Typical 3D object models in the airport fire emergency rescue scene are constructed using three-dimension modeling technologies based on virtual reality.The virtual scenes of fire and firefight special effects are realized by the particle system,and also the human-machine interaction interfaces for both teacher and student positions are developed by Unity 3D engine.The students are supported to enter the emergency virtual drill scene and interact with it by using virtual reality helmet and the handle.The evaluation results demonstrate that the platform meet the requirement of easy-using,stability and real-time,and it could support low-cost,high immersive airport fire emergency virtual drill.
